It was just another one of those “You’re doing X wrong” clickbait videos.
If I had to guess I’d bet they said to buy the whole ribeye or whatever and cut your own.
That's something I’ve been meaning to try but between my tendency to let things go bad before I get around to processing them and my ability to fuck just about anything up I’ve been hesitant to throw down $160 or so to have a go at it.
